The macrobenthos of Sullom Voe
Proceedings of the Royal Society of Edinburgh. Section B. Biological Sciences, 1981SynopsisThe macrobenthos of Sullom Voe was investigated by grab sampling in 1976, 1977 and 1978. These surveys have provided data for future comparisons and have enabled a description to be made of the natural soft bottom macrobenthos of Sullom Voe in terms of species composition and abundance.The most common species encountered were Thyasira flexuosa,

[Bioturbation of macrobenthos on estuarine sediment].
Ying yong sheng tai xue bao = The journal of applied ecology, 2011By using microcosm tracer technique, the bioturbation of macrobenthos Helice tientsinensis, Nereis diversicolor, Bullacta exarata, and Cyclina sinensis on the sediment in Beitang Estuary of Tianjin, China was quantitatively studied. The bioturbation of test macrobenthos had obvious effects on the distribution of the sediment, and the effects differed ...

Recovery of macrobenthos in defaunated tropical estuarine sediments
Marine Pollution Bulletin, 2011In the estuarine environment, hypoxia and/or anoxia have become a major cause of benthic defaunation and are strongly associated with increased eutrophication. Mesoscale field experiments were carried out to examine the recolonization and recovery time of macrobenthos after defaunation.

The historical development of studies on macrobenthic community ecology has been closely related to surveys of fjordic populations stemming from the classical work of Petersen and his successors in Danish areas. This relationship is not fortuitous since fjordic populations are rich, accessible and economically important as the basis of extensive ...

Factors structuring the macrobenthos community in tidal algal reefs
Marine Environmental Research, 2020Tidal algal reefs are considered high biodiversity habitats but have received little attention. Macrobenthos communities were characterized in a gradient of habitat types on the tidal flats in northwestern Taiwan, including algal reefs (R), mixed algal reefs and gravel (RG), mixed sand and gravel (SG) and sand (S).

Macrobenthos and environmental characteristics of the Venice lagoon
Atti della Società dei Naturalisti e Matematici di Modena, 2007Composition, structure and distribution of macrozoobenthic communities in four areas of the Venice Lagoon were investigated. Polychaetes and oligochaetes were the most abundant groups, followed by crustaceans and dipterans and bivalve molluscs. Area differences turned out to be very significant with a maximum diversity index in the central-southern ...

Distribution patterns of Canadian Beaufort Shelf macrobenthos
Journal of Marine Systems, 2008Abstract Variation in macrofaunal composition in relation to sediment and water variables was analysed in nine regions of the western Canadian Arctic on the Beaufort Shelf and in Amundsen Gulf. We hypothesized that benthic community composition was distinctive (1) in a recurrent polynya in Amundsen Gulf and (2) in upwelling regions (Cape Bathurst and

The macrobenthos of the river IJssel
Hydrobiological Bulletin, 1978This survey of the macrobenthos of the River IJssel, a branch of the River Rhine, was conducted in 1973, 1975, 1976 and 1977. The water quality was poor in 1973 and 1976 and relatively good in 1975 and 1977. The numbers of macroinvertebrate species and numbers of individuals in the stone samples taken from the jetties were lowest in 1976 and highest in

Trophic structure of deep-sea macrobenthos
Marine Biology, 1972The effect of the trophic factor on large-scale distributional patterns of deep-sea macrobenthos inhabiting the floor of the World Ocean has been studied. Two hundred and twenty-eight bottom trawl samples collected by Soviet research vessels in the Pacific and Indian Oceans at depths ranging from 3000 to 6000 m were analyzed.

Macrobenthos Diversity Response to Hydrological Connectivity Gradient
Wetlands, 2014The abundant riparian wetlands supported by the complex river network in Pearl River Delta (PRD) are under an intensely anthropogenic disturbance that threatens the local ecological environment. This paper examined the benthic invertebrate diversity and biomass within the Pearl River through a field study.
